2.2 Animating a Sphere

In this lesson you will learn how to create a basic object and how to animate it along a predetermined path.

2.2 Animating a Sphere

Hi everyone, and welcome back to the second lesson of the animating paint strokes in Cinema 4D course. In this lesson, we'll start by creating a sphere and then animating it in the direction that we want our paint strokes to move. So let's think of this as a sort of movement guide. And for this example, I just want to create the paint strokes and animate them in a circular fashion. Which then sort of travels towards the center of the screen like a whirlpool. The next thing that you notice is that I have moved our objects panel. Which was on the right side to the left side. And the reason for this is, so that whenever we try and right click our objects here, we can actually see the options inside our view, inside our screen here. So let's go ahead and firstly create a spline, and to do this we need to go over to the Pen tool, and select Pen. I'm just going to start creating a spline by clicking our first point and then sort of clicking and dragging to make our spline curve, like so. And this is just going to be a simple circular spline, which sort of curves and travels towards the center of the screen like that. And then you can end this line creation process by clicking Esc on your keyboard. You can also adjust the individual sort of points here by clicking on them and then dragging them, like so. So we can just adjust how we want them to look. And we can also adjust the handles here as well. So we can adjust the curvature of this line, by moving the handles around and making them longer or shorter. So that's our spline. The next thing that we want to do now is to create our sphere. Now, our sphere is going to act as our emitter for the brushes. So, to create a sphere, we go over to our Shapes button. Click and hold the button and select Sphere. And now spawn a sphere into our scene. Now it's got a sphere and a spline here. And to connect this sphere to the spline, we need to select our sphere, right click, go to Cinema 4D tags, and select a Line to Spline. Now with a Line to Spline selected, we can go to our Attribute, which is over here. And it's looking for the spline path here. So to attach the two together, we can go and connect the spline, click and drag it, and drop it into the spline path, like so. So now that we've got the spline path connected with the sphere, we can animate the sphere. And to do that, you can see we've got our position options here and you can see by moving it to 100, it moves along the spline like so. So we've got 0%, which is the start of the spline, and then 100%, which is the end of the spline. So now we basically need to decide how long we want our animation to be. So, let's say just 45 frames. So to create this, let's go to 0 as your position, create a keyframe by clicking on to the position here, and then create a keyframe for the end of our animation, which is on the 45th frame. And then let's bring it all the way up to a 100 and then click on the key from here again. So now we've got along our timeline 45 frames of our sphere, moving from point 0 to a 100. So if we click on the Play button. We can see our sphere animating. So there we have it, the sphere, which is animated along the spline path. In the next lesson, we'll go through how to use this animation to create our paint strokes. See you all there.
